NOVELTY - The utility model claims a plastic stool with high strength, comprising a chair surface, a backrest, a supporting leg, a glass fibre layer, a graphene fibre layer, a polyacrylonitrile fibre layer; a metal fibre layer and a reinforcing rod; the left end of the top part of the chair surface is fixedly connected with a backrest; and the periphery of the bottom of the chair surface is fixedly connected with a supporting leg; the upper surface of the chair surface and the right side of the backrest are connected with a polyacrylonitrile fibre layer by PP glue; and the lower surface of the chair surface and the left side of the backrest are connected with a glass fibre layer by PP glue water; at the same time, the outer side of the glass fibre layer is connected with a graphene fibre layer by PP glue. The utility model is provided with a glass fibre layer and a graphene fibre layer, which improves the whole strength of the plastic stool and improves the fire resistance; it is provided with a metal fibre layer and a reinforcing rod; it can effectively improve the strength of the chair surface, the backrest and the supporting leg, so as to further improve the service life of the plastic stool.
